DEYE 35kW Three-Phase On-Grid Inverter, SUN-35K-G04

Download Datasheet Download User Manual Download EU Declaration of Conformity The DEYE SUN-35K-G04 converts the energy generated by photovoltaic panels into three-phase electrical energy compatible with 380/400V utility grids. It is suitable for commercial and industrial installations requiring high output power and flexible photovoltaic array management. Its rated output power is 35kW, while the maximum supported photovoltaic power is 45.5kW. The inverter has two MPPT trackers with three string inputs each, allowing groups of panels with different orientations or irradiation conditions to be connected. The 200–1000V MPPT range and 1100V maximum input voltage provide flexibility when designing the strings. The maximum operating current is 40A + 40A, while the maximum supported short-circuit current is 60A + 60A. The inverter achieves a maximum efficiency of 98.6% and features an IP65-rated enclosure, intelligent air cooling and integrated electrical protection. Monitoring is available through RS485 or RS232, with optional Wi-Fi, LAN, GPRS, Bluetooth or 4G modules.

It does not have a battery input and does not provide backup power when the utility grid is unavailable. The Zero Export function requires a compatible meter or metering system that has been correctly installed and configured. Smart string monitoring, Anti-PID, AFCI protection and certain communication options are optional. Their inclusion must be checked in the supplied commercial configuration. The maximum photovoltaic power of 45.5kW must not be confused with the rated AC output power of 35kW. The PV strings must be sized according to the panels’ Voc, Vmp, Isc and Imp values, the limits of each MPPT tracker and the minimum and maximum temperatures at the installation site. Compatibility with the distribution system operator’s requirements must be checked before purchase and installation. Installation, configuration and commissioning must be carried out by qualified personnel in accordance with the manufacturer’s instructions and all applicable regulations.
